BARREL-BRANDER.

SPECIFICATION forming part of Letters Patent No. 411,561, dated September 24, 1889.

Application filed May 1, 1889. Serial No. 309,180. (No model.)

To all whoml t may concern:

Be it known that I, MAX IULM a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful lmprovements in Barrel- Branders; and l do hereby declare the following to be a f ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to those furnaces which perform the twofold duties of supplying a blast of hot air for heatingl casks and barrels preparatory to pitching them, and also of heating a burning-iron whcrewith the ends of said vessels are branded; and my improvement consists in surrounding the sides of the iron or brand with a bonnet to which a pipe is attached. This pipe has a forced draft that draws the smoke away from the brand, and thus renders the pitching-room of a brewery a more comfortable place for the workmen, as hereinafter more fully described.

In the annexed drawings, Figure l is a side elevation of an apparatus embodying my improvements, the furnace being provided with a pair of brands or burning-irons, and a barrel being seen in contact with one of them. Fig. 2 is a vertical section of one side of the apparatus, taken in the plane of the neck that communicates with said brands. Fig. 3 is an enlarged horizontal section through said neck, but showing a single brand applied thereto.

The furnace proper A is surrounded by a water-jacket l5, and has at bottom a grate e, below which is situated the ash-pit a', into which air is conducted by a pipe C, comuninicating with any desired form of blower capable of affording a pressure of from tento fifteen pounds to the square inch.

D is a short neck projecting laterally from the furnace and leading` into a pipe E, to Whose outer end the brand 'li is attached, as seen in Figi?, the exposed surface of said brand being providedwith raised letters, figures, or other characters f. Finthermore, this brand has a short cylindrical shell Gr, fitting snugly around the pipe E, said shell being pierced at g g to admit a pin ll, which also passes through holes e e of said pipe.

I is a collar fitting closely around the pipe E, and serving as a screen or fender to prevent-the heads of bolts d d being burned olf when the brand is in operation.

Surrounding the pipe E and its attach ments is a bonnet J, having a circular openingj at vits outer end, and at top a pipe for drawing the smoke and gases away from the brand. This pipe is seen in Iiigs] and 2, which illustrations show a duplex branding attachment, the pipe Vlil being provided with lateral branches, (indicated by the dotted lilies l( KQ) and each brauch being provided with a separate burning-iron l.' which irons are secured to said blanches in the same manner as the brand represented iu Fig. il. l'. Il' are bonnets surrounding' these branches, and l'lare pipes attached to the upper side of said bonnets and leading into a common discharge Vllue or exit M, a nozzle N being inserted in the lower end of said exit, which nozzle is attached to a pipe n, communicating with the air-pipe l.

(Y) is a barrel or keg held in a proper position by any suitable means.

l is a cap tilting tightly oyer the end of pipe li when the latter has a pair of brands attached to it.

I'Vhen the apparatus is in operation and a powerful blast of air is forced through the incandescent fuel in the furnace, the heat traverses the neck l) and pipe E, and the brand l" soon becomes red-hot, and is thon capable of burning into the head of the barrel any characters projecting from said brand. lt is evident this branding operation produces considerable smoke, and as the burning-iron is not fitted very closely to the pipe leading from the furnace there is a constant escape of gas and smoke, which noxious vapors would render the pitching-room unfit to work in unless they were speedily disposedof. Now, by referring to Fig. 3, it will be noticed that the openingyl allows a current of air to enter the bonnet J, as indicated bythe arrow, which current is induced by the blast of air discharged from nozzle N. Consequently this current draws the smoke and gases into the bonnet, and thence up the pipes l l into the common exit M, which latter may discharge into a chimney.

It will thus be seen that the above-described IOO deviees serve to ventilate the pitching and branding' room of a brewery Without adding to the running expense of the apparatus.

I elaim as my inventieni. A hot-blast apparatus 0f the class specified having a brand heated bythe furnace7 said brand being surrounded by a bonnet having a smoke-pipe, and a branch pipe 1ead ing from ihe latter te the main air-pipe of the apparatus, whereby a foreed d raft is prod ueed through said bonnet and smoke-pipe, as herein described.

The combination, in. a hot-blast apparatus of the class specified, of the pipe E, branches l( K', brands lr 7u', bonnets L L', pipes l Z', leading from said bonnets te a eoinmen exit M, and a nozzle N, inserted within said exit, whieh nozzle is applied te a pipe n, that eenimunieatzes with the commen air-pipe C, all as herein described.

J3. A het-blast apparatus oi' the elass speeliied having a brand heated by the furnace, said brand being surreulnled by a bonnet havinga smoke-pipe,which pipe has a forced draft, for the purpose herein described.

In testimony whereof I affix my signature in presence of two \\\'ii.nesses.
